ReleasePrimitiveArrayCritical(..) in GetPrimitiveArrayCritical(..) code path!
Now that was quite a miss, causing the bugs in the first place!
The freeze was caused in the JVM, as this open GetPrimitiveArrayCritical(..) disabled the GC.
This was reported via '-Xcheck:jni'.
Depending on the system/jvm, the freeze may happen early or only after a while.
This code path was not executed with new property 'newt.disable.PointerIcon' set,
but from there to finding the missing critical release - a journey:
- jstack showed
"main" #1 prio=5 os_prio=0 cpu=275.71ms elapsed=51.93s allocated=9710K defined_classes=472 tid=0x00007f7084015000 nid=0x1a39 waiting on condition [0x00007f70897c2000]
java.lang.Thread.State: RUNNABLE
at jogamp.opengl.es3.GLES3Impl.dispatch_glUniformMatrix4fv1(Native Method)
at jogamp.opengl.es3.GLES3Impl.glUniformMatrix4fv(GLES3Impl.java:2585)
at jogamp.opengl.es3.GLES3Impl.glUniform(GLES3Impl.java:10713)
-- said that this thread was no more running, waiting on condition ..
-- glUniformMatrix4fv1 was given an array!
- '-Xcheck:jni' gave:
Warning: Calling other JNI functions in the scope of Get/ReleasePrimitiveArrayCritical or Get/ReleaseStringCritical
-- Now it is clear that the lack of releasing the critical array, returning to Java and then calling other JNI methods
caused the Warning - and eventually the freeze.

hence pass PointerIconImpl through

DRM allows 64x64 pixel cursor images, using GBM_FORMAT_ARGB888 only.
Notable: GBM_FORMAT_ARGB888 == PixelFormat.BGRA8888
Having fixed mouse and keyboard input with previous commit,
the demo com.jogamp.opengl.test.junit.jogl.demos.es2.newt.TestGearsES2NEWT
shows via key press
- i -> pointer visible/invisible
- c -> pointer icon change

Adding new classes DRMLib (gluegen of drm + gbm), DRMUtil and DRMMode GBMDummyUpstreamSurfaceHook
to new package jogamp.nativewindow.drm, allowing full awareness of DRM + GBM within NativeWindow for JOGL + NEWT.
DRMMode replaces the previous native code of collecting drmMode* attributes: active connector, used mode, encoder etc
and also supports multiple active connectors.
DRMUtil handles the global static drmFd (file descriptor), currently only the GNU/Linux DRM device is supported.
GBMDummyUpstreamSurfaceHook provides a simple dummy GBM surface.
NativeWindow provides the new nativewindow_drm.so and nativewindow-os-drm.jar,
which are included in most 'all' jar packages.
build property: setup.addNativeEGLGBM -> setup.addNativeDRMGBM
Changes NativeWindowFactory:
- TYPE_EGL_GBM -> TYPE_DRM_GBM while keeping the package ID of '.egl.gbm' for NEWT (using EGL)
- Initializing DRMUtil at initialization
Changes EGLDrawableFactory:
- Using native GBM device for the default EGL display creation instead of EGL_DEFAULT_DISPLAY.
This resolves issues as seen in Bug 1402, as well in cases w/o surfaceless support.
- GL profile mapping uses surfaceless when available for GBM,
otherwise uses createDummySurfaceImpl (dummy GBM surface via GBMDummyUpstreamSurfaceHook)
- createDummySurfaceImpl uses a dummy GBM surface via GBMDummyUpstreamSurfaceHook
- DesktopGL not available with GBM, see Bug 1401
NEWT's DRM + GBM + EGL Driver
- Using DRMLib, DRMUtil and DRMMode, removed most native code but WindowDriver swapBuffer
- ScreenDriver uses DRMMode, however currently only first connected CRT.
- WindowDriver aligns position and size to screen, positions other than 0/0 causes DRM failure
- WindowDriver reconfigure n/a
NEWT TODO:
- DRM Cursor support (mouse pointer)
- Pointer event handling
